das Ding an sich

Last night: Boston Baroque performing Cherubini’s long-neglected Requiem in C minor, paired with Beethoven’s Eroica.  The Sanctus sounded just like the one from Bach’s Mass in B Minor, while the Lacrimosa was lifted straight from the same section in Mozart’s Requiem.  The pre-concert lecture by NEC musicologist Helen Greenwald acknowledged other echoes but perplexingly not these most obvious ones.
